If you haven’t had a gluten free mug cake yet, you are in for a special treat!! But, I am going to be a bit honest, mug cakes are not that “pretty” type of cake. There I said it. You can see above…it needed to be said.

A microwave mug cake cooks at high temperature, in a mug, very fast. It bubbles and rises up over the cup as it cooks. (It is solid, not liquid by the time it rises up so in most cases, it doesn’t explode cake batter thank goodness!)

But, thankfully, this easy microwave mug cake recipe is no exception. One bite is all it takes to get hooked!”

How to make a gluten free vanilla mug cake:

You can make a mug cake without mixing the ingredients separately,  but I like to mix up the wet and dry ingredients separately to ensure everything is well mixed.

Wet ingredients for the mug cake in a bowl.

Step 1: Add the wet ingredients to a small bowl and mix well.

The dry ingredients in a bowl.

Step 2: Add the dry ingredients and whisk to blend.

Step 5: Turn the mug cake upside down on a plate. As I said, mug cakes are pretty ugly. Let the cake cool, then top it with:

  • frosting
  • ice cream
  • whipped cream

Tips and Recipe FAQ:

What kind of mug can you cook a mug cake in?

You can use any type of mug as long as it is microwave-safe!! I have used both glass mugs and ceramic mugs without any trouble.

How long do you cook a microwave cake?

Cook time of a microwave cake can vary by the depth of the mug you use. The typical amount of time needed is around 90 seconds.

How long will a mug cake keep fresh?

This recipe makes a single serving of gluten free vanilla cake. You probably won’t have leftovers, but if you do, it should keep fresh for about 4 days.

  • ¼ cup gluten free flour blend * see note
  • 2 tablespoons sugar
  • ½ teaspoon baking powder
  • tiny dash salt
  • 1 teaspoon pure vanilla extract
  • 1 tablespoon coconut oil melted
  • 1 egg
  • ¼ cup almond milk


  • In a small bowl, add the dry ingredients and whisk to blend.
  • Grab another bowl and add the wet ingredients. Mix well.
  • Add the wet ingredients into the dry ingredients and mix.
  • Pour the gluten free batter into a mug. (The batter should be 1/2 to the top of the mug. If it is a lot higher, use a larger mug.)
  • Microwave your mug cake for 90 seconds. Allow to cool.



  1. I have tested this recipe with King Arthur Measure for Measure GF, Bob’s Red Mill 1 to 1 GF blend, and Authentic Foods Multi Blend in this recipe. That doesn’t mean others will not work, I just have not tested other flours.
  2. If your gluten free flour blend doesn’t contain Xanthan Gum or Guar Gum, please add 1 teaspoon.
  3. You can use any microwave safe mug for this recipe.
  4. The mug handle may be very hot when you remove it from the microwave. Make sure to use a pot holder to remove the mug.
  5. I used almond milk but other dairy-free kinds of milk will work but I do not recommend canned coconut milk.


Please know that every gluten free flour blend has a different starch to grain ratio. If you use a blend I didn’t test, you may need to adjust your moisture levels in your baked goods.
